dies peacefully
Discussion
my car has died peacefully 3 times today no cough no splutter just cuts out, i restart it first time and she carries on like nothing happened!??? any clues
(p.s has started to not like getting out of bed first thing in the morning but is ok when shes got a temp, yes i am still talking about the car)

It's a S3 isn't it ?
Have you checked the immobiliser ? Someone was talking about similar issues the other day and it turned out to be the immobiliser was cutting in.
If not I'd check the ignition wiring to see whether that is shorting or similar.
It sounds definitely like an electrical problem if the engine is cutting out and then restarting without any problems.

Don't know how much experience you have, but unless you're fairly handy with car electrics you might want to get professional help. It is quite easy to make things worse while you're pulling wires around, disconnecting things 'just to check' and so on. But if you do want to investigate it yourself, my guess would be an intermittant electrical fault taking out the ignition, immobiliser or ECU. I start start by taking the lower cowling off the steering column and checking the connector between the ignition switch and the loom. If this is starting to go, you can get all sorts of symptoms from low voltage on the instruments to intermittant loss of ignition, immobiliser resetting and so on. Also reseat all the relays and the ECU connector (in the passenger's footwell). If that dosn't cure it, look for an earth point under the bonnet directly in front of the passenger's feet, check the connection is sound. If the problem persists after all this I'd start worrying about a dodgy immobil
ser or more general electrical fault, and look at more widespread fault finding techniques such as tracking down what is causing the engine to cut out when it dies, and track the failure back from there.
Hope this helps,

If it is the immobiliser, don't waste any more time and get the experts in. and get it sorted. Might want to consider a new alarm depending on was fitted by the dealer when the car was originally sold.
If it was an S1 I would say chcek the relays and connectors in the engine bay by the ignition module. As described in the bible these can get immersed in water and cause exactly these symptoms.

I have an S3C doing a similar thing. I am still living with it at the moment, but have to go away until April, (hence I'll miss any S club Heaven antics, Johno). If I have any bright ideas while i'm away, I'll try and get on the web, but without the car there to tinker with, don't hold your breath!
Good luck with the fault finding, V. Hope the manifold work goes well for you, Johno. Roll on Summer, eh!
See ya, Chin up.
P.S. On mine, it's not the throttle pot, dizzy cap, HT leads, rotor arm, vacuum system, dirty idle speed air control valve or connections.

You can check the sensors and eliminate the throttle pot quite quickly.
Disconnect the throttle pot then drive the car, if there is no stutter you are half way there. Next connect a digital multimeter set to measure resistance to the throttle pot and get someone to push the accelerator pedal. The resistance should change progressively. If the meter suddenly reads open circuit or O/C, then you have a throttle pot problem which can be resolved with £45 and a trip to Henry Ford.

I disagree here. The resistence tests on many of the sensors will tell you if you have a total failure like a O/C or a S/C but they do not confirm that it is actually working.
Throttle pots can have spiky outputs that are caused by cracks in the resistence material that cause problems but are not picked up by a meter. I 've had temp sensors that go O/C intermittently and send the fuelling crazy...
Multimeter tests are worth doing providing yoiu don't assume that if the component passes it is still good!

It is a straight swap.
Waldonway Specialist Cars are a TVR main dealership near Maidstone.
Number is 01732 840935.
It was Keith in the stores who suggested it as an idea and it worked. No problems since.
As an aside did you fit the Green Stuff pads in the end. Are they the right ones as I haven't fitted mine yet as I'm still waiting for the new discs and other bits.
